17th century

[IrishArmenian]

Does a dog bite the hand it feeds? Why would Wladyslaw attack me, for blood is stronger than ink.

If I remember correctly, Sigismund, he was disowned and no longer a member of your family. You seem to contradict yourself here.
You have also said something along the lines of: Wladyslaw will not be a Polish puppet, yet Poland seems to be "the hand that feeds it" (Not the hand it feeds. Could you make up your mind about this?
If this was not a power play, I would remain Tsar and just sign a treatie. Obviously, there is something shady you have in mind. Why else would you endorse two usurpers, one of which is dead and the other is your son, for whom you cannot decide whether or not to disown him as per the contract or keep him in yiur family, therefore defaulting to me as Tsar.
On a much more friendly note, I hope we can both unite against the Holy Roman Emperor. If I am abusing my power, I don't want to know what Emperor Matthias is doing. He must be stopped! All who disagree with him are supposedly his enemies. If I take my main army to his land to assist my ally, Brandengburg, will you help supress uprisings? Matthias will come for you soon, for your deal with us, the Orthodox Rus. He believes he is mandated by God and as such shall fight until all his men are dead. You must help rid the world of the Matthias as soon as quickly. France too, take up arms against the Holy Roman Emperor.
